5. Describe how scientists use modeling.

6. The chart below describes the population growth rate of the red and gray fox in Somerset County Pennsylvania based on observations by scientists over the past five years.  Your task is to complete the chart based on the current population trend. Once you have finished the chart, use the data to create a model.

Answer Key/Rubric

1. Modeling is an explanation supported by data. It can be visual, verbal, or mathematical.
   
   
2. D. All of the above
   
   
3. Acceptable responses might include, but are not limited to:
   
   
   1. Generate new predictions
   2. Test new ideas
   3. Make changes to an existing hypothesis

4. Meteorologists collect data on temperature, wind, air pressure, and wind speed and direction throughout the day. They enter this information into computers, which generate models that map out the weather. Using these maps they are able to predict the weather.
   
   
5. Acceptable responses might include, but are not limited to:
   
   
   1. Explain new observations
   2. Predict future phenomena
   3. Be more realistic

Students should create a line or a bar graph with a title, the X- and Y-axis labeled, and appropriate units on the Y-axis.
